Application October 27, 1939, Serial No. 301522 (Cl. 128-227) L 2 Claims.

This invention relates to syringe bags, more particularly to syringe bags comprising parts so constructed and arranged that one part is movable to position within another part, and the principal object of this invention is to provide new and improved syringe bags.

In the drawing accompanying this specific'ation, and' iorming a part of this application, I have shown, for purposes of illustration, one form which my invention may assume, and in this drawing:

Figure 1 is a broken elevational View, partly in section, illustrating an embodiment of my invention, the parts of the syringe bag being in position to provide a receptacle for containing fluid for syringe purposes, a syringe tube and nozzle being attached to the receptacle thus provided,

Figure 2 is a perspective view showing one part of the syringe bag moved to position within another part,

Figure 3 is a longitudinal sectional view through the bag, with the parts in position as shown in Figure 2, showing the syringe bag attachments positioned within the syringe bag,

and

Figure 4 is a longitudinal sectional view corresponding generally to the line 4-4 of Figure 3, the syringe attachments being omitted from this view.

The embodiment of the invention herein shown comprises a syringe bag ll), having parts H and !2 so constructed and arranged that the part |2 is movable to position within the part ll. Preferably, the part ll is box-like in form, as best seen in Figure 2, and the part !2 is pouch-like in form, as best seen in Figure 1. The pouchlike part |2 is connected to the lower end of the box-like part ll, as shown at l3, the transverse dimension of the pouch-like part l2 at the connection l3 preferably being smaller than the adjacent dimension of the box-like part Il, so that the pouch-like part I2 may be readily moved to position within the box-like part I I. The upper end of the box-like part Il is formed with an opening !4, and cover means |5 is provided to close the opening.

The box-like part ll, the pouch-like part l2, and the cover means !5, are here shown to be formed of rubber, integrally connected, but it will be obvious that these parts may be formed of other and different materials, and may be formed separately and later cemented or otherwise suitably connected. For instance, the pouch-like part l2 may be formed of other suitable flexible material, and the cover means may be formed of any desired material, and may be suitably hinged or otherwise connected to the box-likepart l I. As here shown, the cover means |5 is formed as an extension of the rear wall (referring to Figure 1) of the box-like part ll. The box-like part H may be formed of a suitable flexible or non-flexible material other than rubber, but it has been found preferable to form the box-like part Il of rubber and in such manner that the walls of the box-like part ll are yieldable, yet so constructed and arranged as to assume the box-like form best shown in Figure 2.

The cover means !5 comprises a fiap IB of such size as to close the opening M, the flap being reduced in 'size at its extremity to provide a tab ll which is formed with a button-hola s for receiving a button s, so as to yieldably maintain the cover means |5 in position closing the opening [4. The button |9 is here shown as being formed integral with the front wall (referring to Figure 1) of the box-like part Il. The cover means |5 may also be used to support the syringe bag, and for this purpose is formed with an aperture adapted to receive a supporting member. As shown in Figure 1, the syringe bag` ID is in position for use, and the tab ll is unbuttoned from the button !9, and forms a continue.- tion of the rear wall of the box-like portion ll. A peg 2| extends through the aperture 20, and the syringe bag hangs from this peg.

In Figure 1, the pouch-like par-t l2 is shown extended from its position within the box-like part H, and in this position cooperates with the box-like part H to provide a receptacle for fluid for syringe purposes. The pouch-like part l2 tapers to a reduced outlet 22, a nipple 23 being secured within the outlet 22, and being adapted to receive a coupling 24 attached to one end of a syringe tube 25, the opposite end of the tube 25 having a coupling 28 adapted to receive a syringe nozzle 21, 'a valve 28 being so positioned to control -fiow of fluid through the tube 25.

After use, the tube 25 is preferably removed from the nipple 23 carried by the outlet end 22 of the pouch-like part 12, and the pouch-like part l2 is moved to position within the box-like part l I, as shown in Figures 2 and 3, so as to form an article having a dimension substantially equal to the dimension of the box-like part I I. As will be best seen in Figure 3, the pouch-like part !2, in efiect, formsa bottom for the box-like part l I, and thus provides an attachment receiving receptacle. Preferably, the tube 25 when not in use has a fiat transverse cross-section, so that it may be readily rolled to occupy a minimum of space, the tube 25 being shown rolled in Figure 3,' and being disposed within the attachment receiving receptacle.

The various syringe nozzles 21 may also be positioned within the attachment receiving receptacle, as suggested in Figure 3. The attachments may be held against displacement from the attachment receiving receptacle by moving the cover means l5 to position closing the opening I4, and buttoning the tab |1 on the button !9. With the syringe bag attachments positioned within the receptacle, as shown in Figura 3, it will be apparent that there is provided a c'ompact package which includes the syringe bag and its attachments, and such compact package may be readily stored or transported.

It will be apparent to those skilled in the art that I have accomplished at least the principal object of my invention, and it also will be apparent to those skilled in the art that the embodiment herein described may be variously changed and modified, without departing from the spirit of the invention, and that the invention is capable of uses and has advantages not herein specifically described; hence it will be appreciated that the herein disclosed embodiment is illustrative only, and that my invention is not limited thereto.

I claim:

1. A syringe bag, comprising: a boxlike portion formed of soft rubber f such characteristics that said box-like portion is fiexible yet substantially form-retaining, said box-like portion having an opening at one end for the admission of fluid; and a soft rubber pouch-like portion connected in iiuid-tight relation to the opposite end of said box-like portion and tapering in size to an outlet opening for the dispensing of fluid, said pouch-like portion at said connection having a said pouch-like portion cross-sectional size smaller than the adjacent cross-sectional size of said box-like portion and being so constructed and arranged that it is retrovertible to position within said box-like portion and in its retroverse position forms a bottom for said opposite end of said box-like portion to provide a receptacle for receiving the syringe bag attachments which are insertable through the opening in said box-like portion, and also to provide a. transportable article not materlally exceeding the dimensions of said box-like portion, and being extensible rrom its retroverse position, and in its extended position cooperating with said box-like portion to provide a receptacle for the fluid.

2. As an article of manufacture, a compact transportable syringe bag structure, comprising a tubular portion, the defining wall at one end of which continues in a reverse direction inwardly of said tubular portion, providing a continuing wall so formed that it tapers in defining area toward its extremity to an outlet opening, and is generally co-extensive with a portion of said defining wall to such extent that it steps short of filling the space within said tubular portion, thereby providing an unoccupied space which forms a receptacle adapted to contain the syringe bag attachments, said continuing wall being flexible and capable of movement to a position Wherein it forms a pouch-'like portion extending from said one end and continuing in the same direction as said defining wall, and in such position said tubular portion and said pouch-like portion together constitute a receptacle for fluid for syringe purposes, and single cover means, provided adjacent the other end of said tubular portion, so constructed and arranged that it forms a closure for both the attachment and fluid receptacles.
